Baltimore, Maryland – Residents across Maryland and Delaware should prepare for a wetter-than-average stretch March 5-11, with repeated rain chances that could slow commutes and gradually raise stream and tidal water levels.
According to the National Weather Service Climate Prediction Center, both states fall within a 40 to 50 percent chance of above-normal precipitation during the March 5-11 period. While the signal is less intense than areas farther west, it still supports multiple systems bringing measurable rainfall across the Mid-Atlantic. Temperatures are also expected to trend above average, limiting any threat of widespread snow.
In Baltimore, Annapolis, Salisbury, Wilmington and Dover, most precipitation will fall as rain. Warmer air will dominate throughout the period, although brief cooler pockets could allow a mix in far western Maryland during overnight hours.
Periods of steady rainfall may create ponding along Interstates 95, 83 and 70, as well as Route 1 in Delaware. Poor drainage areas and tidal zones near the Chesapeake Bay and Delaware Bay could see minor water level fluctuations if heavier bands move through.
Residents should clear storm drains, monitor local river forecasts and allow extra travel time during heavier rain. The unsettled pattern continues through March 11, and additional advisories could be issued if rainfall trends increase.
